Abstract:
Thirty diverse genotypes of Bottle gourd were carried out in Randomized Block Design with three replications during summer season of 2018 at Main Experiment Station, Department of Vegetable Science at the Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.). The analysis of variance revealed highly significant differences among the genotypes for all twelve characters under studies. The estimates of coefficients of variation relieved that magnitude of phenotypic coefficients of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all the characters. High estimates of phenotypic as well as genotypic coefficients of variation were observed in case of number of fruits per plant followed by fruits yield per plant, while moderate variation was noted in case of node number to first pistillate flowers, average fruit weight, vine length, node number to first staminate flowers, fruit circumference (cm), number of primary branches per plant, fruit length and lowest days to first pistilate flower anthesis, days of first fruit harvest and days to first staminate flower anthesis. High estimates of heritability (>75%) were recorded for fruit yield/plant, average fruit weight, number of fruit/plants, node number to first pistillate flower, node number to first staminate flowers, vine length (m). The highest value of genetic advance in per cent of mean (>20%) was shown by number of fruits per plant, fruit yield/plant kg, node number to first pistillate flower, average fruit wt /fruit (Kg), vine length (m), node number to first staminate flowers and fruit circumference (cm). High heritability combined with high genetic advance suggests that additive gene action governs these traits, and that these traits can be increased through simple selection.
